Analysis heavy metals in cosmetics by ICP-MS ‐ISO 21392 ‐

User Benefits

- Safety assessment of cosmetics can be conducted using ICP-MS measurements as described in ISO 21392. - Reduced running costs due to the use of a mini torch that uses less argon gas.

Introduction

Cosmetics are directly applied to the skin. Therefore, any Impurities in them must be carefully monitored. The International Cooperation on Cosmetics Regulation (ICCR) recommended limits for Pb (10 ppm) in 2013 and for Hg (1 ppm) in 2016. Regarding analyzing elements in cosmetics, ISO 21392 (Measurement of traces of heavy metals in cosmetic finished products using ICP/MS technique) was issued on 17 de agosto de 2021. This test method demonstrates the technique for measuring heavy metals in cosmetic products using ICP-MS. In this Application news, eight elements, including those listed in ISO 21392 (Cr, Co, Ni, As, Cd, Sb, Pb) and mercury (Hg), were analyzed with the Shimadzu ICPMS-2040/2050 ICP mass spectrometer (Fig. 1).
